ofxUIScrollableCanvas with fbo

Hei ppl,

Me and Carles @charli_e have been working a bit on ofxUI (best ui ever) to get a scroll bar using fbo.
We wanted to have an fbo so that the widgets can be cut when hitting the border of a canvas. I have a branch here:

It has an example showing the new goodies.

It needs to be polished and there are still many things to be improved:

  • fbo alpha blending issues… maybe some guru can fix that…
  • scroll on X axis needs to be done.

If @reza is around… let me know if you want to integrate it to your repo… probably it needs more polishing before that.

awesome! Thanks guys, I’ll check this out next week when I get a second!

hey @Jordi, thanks for this! i would like to use it to make a scrollable like image picker. I tried the branch of the example and it works on 0.9.8/last Xcode & Sierra, but:

the reza version is more recent… 2 years earlier. there’s any easy way to update your branch to this one? or I should use all your version? what branch?


Sorry its been a really long time i don’t use ofxUI.
Lately I use ofxImGui instead. did you give it a try? it does all these things for free.

I just tried my old code. The branch example-scrollbar is what you are looking for. It has my-example-Scrollable.
Project files might be wrong.
You might have to remove these files from the VS project:


and add:


As I said on 3 years ago there are issues on FBO blending… good luck!
